- Only certificated person is allowed to do installation, operation and maintenance.
3 INSTALLATION SITE
There is flammable refrigerant in the unit and it should be installed in a well-ventilated site. If the unit is installed inside,
an additional refrigerant detection device and ventilation equipment must be added in accordance with the standard
EN378. Be sure to adopt adequate measures to prevent the unit from being used as a shelter by small animals.
Small animals making contact with electrical parts can cause malfunction, smoke or fire. Please instruct the customer
to keep the area around the unit clean.
The equipment is not intended for use in a potentially explosive atmosphere.
Select an installation site where the following conditions are satisfied and one that meets with your customer's approval.
- Places that are well-ventilated.
- Safe places which can bear the unit's weight and vibration and where the unit can be installed at an even level.
- Places where there is no possibility of flammable gas or product leak.
- The equipment is not intended for use in a potentially explosive atmosphere.
- Places where servicing space can be well ensured.
- Places where the units' piping and wiring lengths come within the allowable ranges.
- Places where water leaking from the unit cannot cause damage to the location (e.g. in case of a blocked drain pipe).
- Do not install the unit in places often used as a work space. In case of construction work (e.g. grinding etc.) where a lot of
dust is created, the unit must be covered.
- Do not place any object or equipment on top of the unit (top plate)
- Do not climb, sit or stand on top of the unit.
- Be sure that sufficient precautions are taken in case of refrigerant leakage according to relevant local laws and regulations.
